Ubuntu in Azure DNS Name Change - azure

I was wondering if I could change the DNS name on one of our azure servers from ######.cloudapp.net to mail.flyboeingva.org?
If so, how would I go about doing this?

Yes you can!
follow the tutorial Configure a custom domain name for Azure cloud service. Further more, if you are going to host e-mail server on azure, you may also want to:
Reserve an IP Address for your cloud service (your VM runs in a cloud service, don't get confused by the terms)
Register Reverse DNS record (PTR) for your cloud service / custom domain

Azure DNS for country Domain

I want to use my country domain which is mydomain.id after setting up in my azure DNS and domain provider, I still cannot validate my domain in App Service. I already double-check everything and I think my settings are already correct. Now I wonder can we use the Country domain in my azure DNS because I'm afraid if it's that the problem.
First of all, I assume you are using a public domain. As Martheen's comments mentioned that you just need to create DNS records to map your app service IP or hostname like webapp.azurewebsites.net in your DNS provider so that you can add custom domains in your App Service. This is tutorial.
Azure DNS is a hosting service for DNS domains that provides name resolution by using Microsoft Azure infrastructure. By hosting your domains in Azure, you can manage your DNS records by using the same credentials, APIs, tools, and billing as your other Azure services. You have the option to host your records on Azure DNS.
After adding the DNS records, you can use the local tool nslookup or websites https://dnschecker.org/ to check the DNS propagation. It can take up to 72 hours to propagate worldwide, although it typically takes a few hours.

Point Azure VM to Local DNS

I feel like I may be trying to sprint before I can even walk here, but I'm getting there! I've got a VM on Azure that I want to be able to access a local fileserver from. We have the following setup:
$COMPANY.net is the local domain, $COMPANY.com is the Azure domain. They are connected using Azure AD Connect, and the VM on Azure is using AADDS; we have a site to site vpn setup between Azure and our local network. I can put in the IP address of the local fileserver and reach it from the Azure VM, but I can't resolve the name if I try that. I believe it is a DNS problem, I need the Azure VM to use my local DNS server to resolve the host name rather than the AADDS addresses. Do I need to set up a DNS server on Azure that will point the requests to my local DNS, or is there another way?
Thank you!
You can specify DNS server for your Azure VM to use. The doc is quite large: https://github.com/MicrosoftDocs/azure-docs/blob/master/articles/virtual-network/virtual-networks-name-resolution-for-vms-and-role-instances.md
Your name resolution needs might go beyond the features provided by Azure. For example, you might need to use Microsoft Windows Server Active Directory domains, resolve DNS names between virtual networks. To cover these scenarios, Azure provides the ability for you to use your own DNS servers.

How To setup Azure DNS server

I want to change name-server of my domain, but Azure websites services only offer CNAME and not name-server, Somebody told me we can host our DNS on Azure using virtual machine,, So anybody here which can provide all steps to create DNS server on Azure and how to setup name-servers out of it?
This isn't a direct answer to your question but more a suggestion.
You can host your DNS records in Azure using Azure DNS (currently in public preview).
Here are some more information about the service https://azure.microsoft.com/en-us/services/dns/ and steps required to get the service working https://azure.microsoft.com/en-us/documentation/articles/dns-getstarted-create-dnszone/.

SMTP on Azure VM - Public IPs (PIP) and Reverse DNS lookups

Azure recently introduced PIP - Public IPs that can be assigned to Virtual Machine instances, however it appears that there is no way to assign a PTR record to that IP so that a reverse DNS lookup will be successful. Here are the instructions to assign a PIP to an Azure VM:
https://azure.microsoft.com/documentation/articles/virtual-networks-instance-level-public-ip/
We have VMs on Rackspace Cloud running SMTP services that I'm trying to duplicate on Azure, but there appears to be no way to assign a PTR record for your Azure PIP. As a result, we are unable to provide our own SMTP service on Azure. Rackspace Cloud assigns a public IP address, and allows you to edit their DNS PTR records for that IP address and assign it to your service. Is there any way to do something similar with Azure?
BTW: SendGrid and Amazon SES are not an option. We've been running E-mail servers for decades responsibly, unless we can get a VM with a public IP and DNS setup properly, Azure isn't a viable option.
Now to the good news: I just learned that this is something they are actually working on right now!

Announcing: Reverse DNS for Azure Cloud Services

Enjoy....
Yes, but the outgoing IP is different then the VIP one for which you create the reverse unfortunately
The name resolution service provided by Azure is mainly designed to access virtual machines and role instances within a cloud service by hostname directly.
To access your public endpoints by name in this case, I recommend deploying your own (using your existing) DNS server(s) with all the flexibility it offers for creating A, MX, PTR etc. records.
For more information on name resolution scenarios, please review https://azure.microsoft.com/en-us/documentation/articles/virtual-networks-name-resolution-for-vms-and-role-instances/.

How do I provide my own FQDN for my hostnames?

I am searching the documentation on how I can provide my own FQDN to my hosts in Azure but don't seem to find what I need. How are you all setting your FQDN so that you can access your different host systems by that name instead of name.cloudapp.net
I essentially want to access it by machine.domain.tld (where domain.tld is my own domain name)
What you are looking for is probably the support documentation regarding DNS Services and configuration of Azure Cloud services.
Microsoft Azure Support Pointers
I found a support article on the configuration of a custom domain name for an Azure Cloud Service.
I am not sure if you are asking about configuring DNS for a Web Site service, which looks like it has different instructions so choose appropriately.
Make Changes with Your Domain Registrar
Depending on whom you have registered your domain name with, you will need to set up a DNS A Record and a DNS CNAME to get what you need.
The "A Record" is where the domain.tld value is assigned. It will be the same as your cloud service public-ip. The machine name represented in your assigned DNS address is associated with a Domain C-Name record established with your Domain name Registrar and pointed to your A Record.
Follow the instructions to also configure your cloud service settings. Pointing the domain name to your cloud service will not be enough.
